Product Description

Magnesium Fluoride Crystal (MgF2)


Magnesium fluoride crystal (MgF2) belongs to the tetragonal crystal system, with a melting point of 1255 ℃, high hardness, good mechanical properties, stable chemical properties, and less prone to deliquescence and corrosion. The main characteristic of its optical performance is its high transmittance in the vacuum ultraviolet band. It is widely used in fiber optic communication, military industry, and various optical components.
